I've noticed something really interesting on a couple AA codeshares out of Phoenix lately. All the AA codeshares used to sit well in excess of $1,000. Seems like some are getting repriced now. Of course, there's zero seat availability since AA blocks most of the plane.

PHX-PDX (still one AS nonstop for 3/4 of the year) is priced outrageously high ($400+ in late June, and WN/AA are around $250).
PHX-SEA-PDX (AS to SEA, QX or AS mainline to PDX) was priced between $250 and $550 depending on flights.
PHX-SJC-PDX (AA to SJC, AS to PDX), routinely hits $1,500 o/w in coach.
PHX-SLC-PDX (AA to SLC, AS to PDX), $320, though this is routinely the "cheapest" codeshare I've seen on this route
PHX-SAN-PDX (AA to SAN, AS to PDX), $320
PHX-SNA-PDX (AA to SNA, AS to PDX), $712
PHX-SMF-PDX (AA to SMF, QX to PDX--will there be a crew to fly the Q400?) $320

I priced these out for a one way trip booked ~3 days out around June 27. Looks like they're similarly priced today for July 14. Of course, the WN and AA nonstops are running $200 and WN has some decent times that work with my schedule.

Of course, if I want to fly to CLT or MCO, it costs me almost $2,000 and takes anywhere between 21 and 30 hours, and I get to fly PHX-SEA-ORD-CLT or PHX-SEA/PDX-SFO-MCO.
